SPECIFICATION forming part of Letters Patent no. 504,440, dated September 5, 1893. Application filed March 15, 1892. Serial No. 424,997. (No model.) Patented in England August 17, 1891, No. 13,834.

To all whom it may concern.-

Be it known that I, HARREY MOORE, a subject of the Queen of Great Britain, residing at Wellingborough, in the county of Northampton, England, have invented new and useful Improvements in and Relating to Wheels of Road-Vehicles, (for which I have applied fora patent in Great Britain,No. 13,834, bearing date August 17, 1891,) of which the. following is a specification.

This invention relates to improvements in the construction of wheels whereby the spokes may be extended between the hub and the felly in order to obtain-the necessary rigidity in the wheel; to the means of distributing oil upon the axle automatically by the rotation of .the wheel, and to the special form of tire employed for the wheel.

. I make and construct the wheel as shown in the accompanying drawings, in which- Figure 1 is a front elevation of my improved wheel. ,Fig. 2 is a cross section through the folly showing the form of the iron tire. vFig. 3 is a cross section through the telly showing a modification in form of the iron rim suitable for receiving an india rubber tire. Fig. 4 is a sectional view of the hub, the spoke extending mechanism being shown in its con-- tracted form. Fig. 5 isa section taken at the line a b in Fig. 4., showing'the application of .thespokeextending wedges to the spokes.

Fig. 6 is an elevation of the radial mortise plate. Fig. 7 is a plan of Fig. 6. Fig. 8 is a side View and Fig. 9 is-a plan of one of the spoke extending wedges. Fig. 10 is a sec-v tional view of the hub the spoke extending mechanism being shown in its expanded form. Fig. 11 is. a section taken at the line 0 d in Fig. 10 showing the expansion of the spoke extending mechanism. Fig. 12 is an elevation and Fig. 13 a plan of the cone employed for. the spoke extending mechanism. Fig. 14 is a sectional view of a modified formof hub employing two cones for the spokeextending mechanism which in this figure is shown in its contracted form. Fig. 15 isasection taken upon the line 6 f in Fig. 14. Fig. 16 is a sectional view similar to Fig-14 the spoke extending mechanism being shown in its expanded form and the oil box and oil cap applied thereto. Fig. 17 is a front elevation of the modified form of radial mortise plate as adapted to the spoke extending mechanism shown in Figs. 14 and 16. Fig. 18 is a side elevation of Fig. 17. I

Upon the axle-box and secured thereto by the pins (1 d I provide a radial mortise plate A having a number of undercut radial grooves corresponding with the number of spokes to be put in the wheel. In these radial grooves wedge shaped bars Bare secured capable of moving therein so as to close toward the center of the axle-box C until they all meet laterally forming a cylinder having a conical bore. These. wedge shaped bars B together with the axle-box O are fitted into the nave of the Wheel so as to bring one of these bars B to face each of the mortises D of the nave in which the spokes are fitted. Thus the wedge shaped bars B form bases upon which the spokes E rest within the nave of the wheel and as they are movable in the radial grooves of the radial mortise plate A they may be expanded by means of acone F screwed upon the axle-box 0 within the nave of the wheel so as to extend the spokes from the nave toward the telly and thus put the required strain upon the wheel to obtain the required rigidity. The cone F being screwed upon the axlebox 0 by means of a right hand screw thread formed thereon, may be securely retained by a following nut Gr engagingwith a left hand screw thread G formed upon that part of the axle-box C which projects beyond the, cone F. The axle-box O has at its rear end a cylindrical box H secured thereto by the screws ff made for rcceiving a store of oil admitted through an orifice, in a dust proof case K closed by a -:screw L. This orifice may be made to correspond with a passage a through a tube 1) fixed in the oil-box H and projecting therein radially as nearly as possible to the axle M which passes centrally through the oil-box H and the axle-box O. The tubular projection 11 serves for filling the oil-box H to about the level of the central opening therein through-which the axle M passes and acts as a dipping peg passing once through the body of oil contained in the oil-box H at each revolution of the wheel and depositing upon the axle M drops of oil which drain from the dipping peg b as it passes out from the oil in completing. each revolution of the Wheel. .The oil thus deposited upon the axle finds its way along by suitable oil channels out upon the axle M or within the axle-box O and may drip from the axle M at the outer extremity of the nave of the wheel into a hollow nut N screwed on to the cone F as shown in Figs. 4 and or into the axle-box C as shown in Fig. 16. The hollow nut N forms a reservoir in which the oil after lubricating the axle is collected.

In order to protect the oil-box from ad- I wardly inclined flange g at eachside projecti ing toward the center of thewheel. The exltension ofthe-spokes thus tends to force the felly hinto the tapering channel which the flanged tirerepresents and so securesthe tire upon the wheel without spikes or bolts by which ordinary tires are secured to the-fellies of wheels. In case of employing anindiarubber tire I makethe rim in the form shown in Fig. 3 toreceive the india-rubber tire 70.:

In thecase of wheelsintended for heavy vehicles I make a modification in the-spoke extending mechanism to provide for expanding I the wedge shape bars by two cones instead of one. 'The modifications are shown in Figs. 14,

i I 15, 16, 17 and 1s.

-The axle-box O isgrooved at its centerto receive the mortise plate Pwhich is cut in. two-halves for placing it in the recess or. groove Q. One of the cones Fhas a left. --hand screw thread-Iand the other \Fhas a wright hand screw thread the axle-box 0 being -correspondingly threaded in a'left hand direction at one-side of the groove onrecess Q wand in a right hand direction at the other side; .1 These cones" F! and F- areguided in 1. a the nave of the'wheel by projectionsil forming feathers to slide in grooves m made in the nave so that the cones-may be made to apwproaoh to or recede from eachother without rotating, by rotating the axle-box O by means s ofa suitable spanner applied at n.

applied by the screws ff after expanding bars B to keepthese bars in position to bear evenlyupon the spokes E which rest upon them to be extended thereby in accordance. with the pressure brought to 'bearxby enter- In this. case theoil box H is -the spoke extending mechanismwhich is se- -curely fastened byithe lock nuts 12 and 12';

Then the wheel is put upon the axle Mupon,

w What I claim, and desire to secure by Letters Patent, is-

1. In a wheel the combination with the nave the spokes passing through mortises in the nave and the axle box, of a plate secured to the axle box and having radial grooves, of a series of wedges whose ends are adapted to slide in the radial grooves of the plate and whose outer surfaces bear against the inner ends'of the said spokes, and of a cone adapted to be moved along the axle box and act on the inner surfaces of the wedges to force them outward radially substantially as specified.

2. In awheel the combinationwith the nave the spokes passing through mortises in the nave and a screw threaded axle box, of a plate secured to the axle box and provided with radial grooves, of a series of I wedges whose ends are adapted to slide radially in the saidradialgrooves and whose outer surfaces formportions of a cylinder parallel to the axle andwadapted toform bearing surfacesforMthe-inner ends of the spokes and twhose'inner surfaces form portions of a cone coaxial withnthe axle box and of a cone adapted to be screwed on the axle box and to force the wedges radially outward substantially as specified.

3..
